invention relates to improvements.-

having particular reference to a machine for use in sawing or dividing elongate work pieces Into a a plurality of parts. I

1 One of the purposes of the present mvention' is the provision of a machine which shall be automatic in operation in that it will selectively engage individual work units from a hopper containing a quantity of such units, will properly support said units,- line them up to best advantage in the machine, resent them to suitable cutting mechamsm and subsequentl discharge the cut or severed arts in di erent places or into diflerent bmsorreceptacles and will separate the usable work pieces from the waste or scrap ends.

Other objectsof the invention will be apparent by reference to the drawings taken in connection with the accompanyin specification and claims, the drawings il ustrating one form of embodiment of the princif the machine with ples of my invention. Fig. 1 is a plan view 0 I parts broken away;

Fig. 2 is a sectional view as on the line 22ofF ig.1;

Fig.- 3 is "an enlarged fragmentary sectional view illustrating the work guiding members; Fig. 4 is an enlar fragmentary front elevation of the wor carrier or conveyor I and associated parts; I FFig. -5 as section ,on the lifie of 6 is a view of one form of work" r: ti; drawings 10 d tea the as e em a frame of a machine my inven- -tion having mounted thereon a hopper. 11 'for the .work pieces which maybe m-the- .form of tubes 12. These tubes when produced bi extrusion have the fragmentary end we] 13, .as shown in Fig. 6. Tubes 2 of thecharacter Qhere illustrated fo13med I from very thin copper or the like are frequently emplogpd mi the-manufacture of automobile ra 'ators where a number of i 3; and.

: eo fshort sections are assembled together. One

use "of the present machine therefore-is in the'severing .of a long-tube such as 12 into-a plurality of individual tube units .or work pieces 14fof proper length and at. the same time eliminate the defective or nonusable end portions 13. w

In the accomplishment of this result I make use of a. drum or carrier 15 havingthe. hub portions 16 secured on the shaft' 17, said shaft having a worm gear 18 meshing with the worm .19 of v the drive shaft 20 for'slow rotation. The-drum is provided with the transversely extending grooves or A recesses 21 to receive tubes or work pieces 12 fromthe hopper 11. An adjustable guide 55 or' gage member 22, carried by a portion of the frame '1, depends immediately adjacent the periphery of the drum holding. back all but a single work piece from each" of the-recesses so that no extra pieces will be carried out of the hopper. This member is adjustable as by the swivel screw 23 and is locked in adjustedposition by a set or clamp screw 24, guide fingers 25 cooperating with the member to limit riding of the work pieces when the hopper is The drum, illustrated in Fi 4, rides; at the ri ht hand side of the mac eagainst a gui e plate 26 having aportion vof U-shape in cross section as indicated 50 in FIgS. 3 and 5 providing a channel in wh1ch the small sections 28 out off the right hand ends of the tubes may ride downward away from the carrier into a suitable rece tacle. v o properly line up the tubes for-the'cutting operation, Imake use of a nozzle 29 directmg an air blast as'at 30 against the tubes as they rest at the top of the drum, the

tubes being so. light that the air blast will move thein o ver' untiltheir ends rest and ride against the-abutment late Carried b the stander '31 adjacentthe ends of the rum the'rod or-shaft 32 which may be'lockedin rotatably adjusted position by tigthetening of. the split'bearing' 33. This-rod arsia tp'lurality of collars around which pass e tension bands 35 each secured in placeby thescrew 36 which passes through the'collar intoclamping enga 5 0 ment with the shaft 32 to retain the colifr in desired rotatably adjusted position with respect to the shaft or-r'od. These tension bands extend'downwardly a distancearound the carrier and have their other ends extending outward between the clamp plates ioii during and subsequent to the severing operation, make useof the hook-like members 40 which as shown fit over the bands and collars 34 and have suitably secured thereto the contact plates 41. These lates are curved to fit around the carrier ing held tightly thereagainst at the cutting position,

and extending predetermined distances be: yond said position. For example, the central guide members preferably terminate substantiall at the omt 42 as indicated'm Fig. 3 whi e the le t hand end member is shown as extending through a considerably greater arc, thus retaining the severed tube section or end in place until the terminus of the band is reached when it is free to drop out of carrier groove. In this manner, by varying the length of the uide members 41, I readily control the disc arge of the severed tube sections of any part1cular row.

I To perform the cutting operation I journal in suitable bearings as at 43, te shaft 44 provided with the spacing members 45 and clam ing flanges 46 between which are secured t e saws or cutters 47. The saws are designed to operate in the circumferential grooves 48 of the carrier drum, these circumferential grooves being greater in depth than the depth of the work receiving coves-21 so that the saws may pass down into these grooves and will entirely sever the tubes or work pieces 12 into the desired number of parts of exactly prescribed len th. Power for the sawing operation is applied to the saw shaft by means of the belt pulley 49 driven from a suitable source of power.

Connections 51 are rovided for directing 'a pneumatic or other last as at 52 against the saw and work at their point of operative engagement to clear awa chi s and to revent any tendency toward over eating of th parts during the cutting operation.

The parts having been suitably severed it is desirable that theybe lpositively removed from the carrier or that t e removal be, positively insured so that there will be no clogging up or interfering with the o ration of the machine on the next TGVOlIItlOIlQ In the accom lishment of this result, I mount either in t e saw grooves or in suitable supplemental annular grooves 53 intermediate the saw grooves the cam-like ejector fingers 54. These fingers as illustrated in Fig. 2 ride in the bottom of the grooves so that mamas parts will be positively removed from the carrier. Thus the grooves as they move upward into the hbp'per will be unobstructed so that each groove may properly receive a tube to be operated upon by the machine.

While I have shown and described a specific embodiment of the invention I do not wish to be limited to the shape, size and arrangement of the parts herein. shown and described but merely by the scope of the appended claims.
